Uncertainty in Signals of Large-Scale Climate Variations in Radiosonde and Satellite Upper-Air Temperature Datasets
There is no single reference dataset of long-term global upper-air temperature observations, although several groups have developed datasets from radiosonde and satellite observations for climate-monitoring purposes. The existence of multiple data products allows for exploration of the uncertainty in signals of climate variations and change. This paper examines eight upper-air temperature datas...
متن کاملUNCERTAINTIES IN CLIMATE TRENDS Lessons from Upper-Air Temperature Records
and reconciling rapid surface warming with upper-air temperatures, which were reported to have exhibited little if any warming over the satellite era (Folland et al. 2001; NRC 2000). This has led to a number of new satellite(Christy et al. 2003; Mears et al. 2003; Grody et al. 2004), radiosonde(Lanzante et al. 2003; Thorne et al. 2005), and reanalyses(Uppala et al. 2005) based upper-air tempera...
متن کاملReference quality upper-air measurements: GRUAN data processing for the Vaisala RS92 radiosonde
The GCOS (Global Climate Observing System) Reference Upper-Air Network (GRUAN) data processing for the Vaisala RS92 radiosonde was developed to meet the criteria for reference measurements. These criteria stipulate the collection of metadata, the use of well-documented correction algorithms, and estimates of the measurement uncertainty. An important and novel aspect of the GRUAN processing is t...
متن کاملSensitivity of Tropospheric and Stratospheric Temperature Trends to Radiosonde Data Quality
Radiosonde data have been used, and will likely continue to be used, for the detection of temporal trends in tropospheric and lower-stratospheric temperature. However, the data are primarily operational observations, and it is not clear that they are of sufficient quality for precise monitoring of climate change. This paper explores the sensitivity of upper-air temperature trend estimates to se...
متن کاملTemporal Homogenization of Monthly Radiosonde Temperature Data. Part II: Trends, Sensitivities, and MSU Comparison
Trends in radiosonde-based temperatures and lower-tropospheric lapse rates are presented for the time periods 1959–97 and 1979–97, including their vertical, horizontal, and seasonal variations. A novel aspect is that estimates are made globally of the effects of artificial (instrumental or procedural) changes on the derived trends using data homogenization procedures introduced in a companion p...
